The thing is, I have character art of the 'mystery' character on my pc here, along with Breakdown's vehicle mode...I thought they belonged together. He even has the same stance as that Breakdown image..

It's NOT Breakdown. He's a Decepticon, a scout, and it's a good bet he transforms into a car, but which character from the dozens of Decepticon characters he is, no one knows yet. He could be Wildrider, Dead End, Runamuck, Runabout, he could even be named after a Decepticon micro-TF. What I hope he's not called is Barricade. I'd prefer it if this game steers clear of any movie-based TF characters.

I'm going to go out on a limb and say Reflector. He's a small scout sized character. His color scheme (minus the green chest) and head shape are similar to the cartoon guys (if you squint). And his wheels kind of look like old camera lenses. If they can make a cassette player into a truck, why not a camera into a car?

While it could be a drone or even an example of the create-a-bot (thus the colors can confuse us all), it does indeed give off a Astrotrain vibe. If I had to take a 2nd shot in the dark...... Motormaster? (Then again, his name is so taboo now along with the Menasor/Scourge/Nemesis linking, it's doubtful)

My money would be against Astrotrain; there's been no talk of triple changers being implemented for play, though it would be nice if I was wrong. Besides, the body type more closely resembles the Megatron and Brawl characters. When I first saw this character my immediate thought was a wheeled version of Megatron, only with a different head.
